Everyone has the same footage I have.
Not necessarily, and I might be mistaken, but it doesn't look like we do.
Unless you have sent us the exact same file, we probably don't. Whenever you use a tool to cut or edit a video in any way, when you save it, it usually recompresses it, meaning it changes it losing some quality.
You're showing some snippets from close to the beginning of the first video above (UFO 1080P -1.mp4), right before and as the car starts moving.
I can't see any of that when I watch that video. All I see is a very faint smudge that appears and disappears, the power lines are pixelated staircases. In your prints the smudge looks less faint and the power cables are more like lines.
Not that this will help identifying the object, I think it's pretty close to settled right now, but it's useful to know.
I have downloaded the first of the last two videos sent, used ffmpeg to extract every frame from second 22.000 to second 25.000 as a png file (which doesn't recompress it), and that gives me 90 frames.
I can see nothing in the first 44 frames. At frame 45 (which would place it at 23.500 seconds in the video), it looks like the car goes through a shadow, which makes the windshield a bit less bright, and a small speck is visible right below a power line. I have cropped and used ImageJ to
resize it without interpolation - so we can see what actual pixels are in the image - below. First with some of the context around it.
Then another crop and resize (no interpolation) to see that it's a very low information 4x6 pixel rectangle.
Below is the object at frame 67, first version it has been scaled without interpolation (actual pixels), second is with bicubic interpolation. Most of the time, we have no idea what type of interpolation is being used when we resize an image, but some variation of bicubic I think still is a popular method.
Does it "look like a plane"? I mean, sure. It looks like a plane as much as it looks like anything else as a 3x4 pixels out of focus rectangle.
